#  The checksize script verifies that the kernel image doesn't grow too
#  large in order to fit into a certain amount of memory. MAXSIZE defines
#  that amount of memory. It represents the number of kB typically available
#  in a PC starting from 0x98000 up to the extended BIOS data area. STACKSIZE
#  defines the name of the file which contains the size of the stack in bytes.
